GANG-PLOW.

SPECIFICATION forming part of Letters Patent No. 447,724, dated March 3, 1891.

Application filed June 25, 1890. Serial No. 356,618. (No model.)

To all whom it may concern:

Be it known that I, LEWIS GIBBS, a citizen of the United States, and a resident of Canton, county of Stark, State of Ohio, have invented a new and useful Improvement in Gang-Flows, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

IO My invention relates to improvements in gang-plows 5 and it consists in providin g means for guiding or changing the line of draft and for holding the plows to the desired line.

lVith these ends in view my invention consists in certain features of construction and combination of parts, as will be hereinafter described, and pointed out in the claims.

Figure l of the accompanying drawings is a View in perspective from right front illus- 2o trating myinvention. Fig. 2 is a similar view from left rear. Fig. 3 is a similar view of the front of the beam, showing the manner of connecting the guiding-tongue and clevis. Fig. 4t is a side elevation showing the manner 2 5 of connecting the switch-wheel to the plowframe. Fig. 5 is a perspective of a lockinghub by which the furrow-wheel yoke is locked to the guiding-lever.

As my invention is applicable to gang- 3o plows now in use, aud particularly so to the gang-plow shown and described in Letters Patent granted to me bearing date the th day of April, and No. 402,155, I will proceed with the description, referring to other parts of the plow only as conjunctional thereto.

Calling attention to Fig. l, A and A represent the plow-beams, which are parallel, as shown; B, the plows; O, the supportingwheels, and D and D the cranked and divided axles.

To the front end of the beams AA there is secured a clevis composed of the jaws a, having flanged edges a to form a socket a to embrace the front end of the beams, and a se- 5 ries of perforations a placed in vertical order at the front portion of the jaw, in which is placed a cross-bar a that may be adjusted vertically in the said perforationsyby which the line of draft may be adjusted vertically.

On the bar a and between the jaws is placed a sliding portion of the clevis consisting of a sleeve portion a having a rearwardly-projected loop a, a stop a and in front of said sleeve and integral therewith a laterally-projected portion a having a series of perforations a, in which the draft chain or link a may be secured in desired lateral adjustment. A bar 12 connects the top portion of the jaws a and serves as a support for the sliding tongue-support G, said support having a sleeve portion 12 to slide on the bar I) and a socket b to receive the tongue. A plate I), having a series of perforations b to which the front end of the shifting lever H is pivotally secured, is provided with arms that embrace the bar I) at each end of the sleeve b which serve to move the sleeve on the bar as the lever H is moved. On the front end of said lever are provided jawsbi, which are connected by a vertical rod b which passes through the loop a and engages the stop of. The rear end portion of the tongue is secured in the socket b by the bolt 11 The lever H is pivotally secured to an arm I), projected from a sleeve 1), secured between 7 5 the beams by a through-bolt, and is secured in desired lateral adjustment by the engagement of a spring-actuated bolt of the usual form with the teeth of the rack d.

To the beam A is secured a forwardly- 8o curved standard K, having secured thereto in a sliding relation a correspondiugly-curved rack L, having elongated apertures d and rearwa'rdly-projected teeth (1 Said rack is held in position by bolts d passed through the apertures d, on which the rack may slide. A coil-spring d is provided, as shown, having one of its ends secured to the end portion of the standard K, the other to the upper end of the rack L, the energy of which is exerted 0 against the rack.

On the axle D is secured a sleeve 61 having on one of its ends a segmental rack 61. The end of the axle D is passed into the sleeve d and is held in engagement therewith by 5 the lock-lever (Z T o the segment (I is secured a hand-lever M, having a spring-actuated locking-bolt of the usual form to engage the teeth (1 of the rack L. The levers H and M are extended rearwardly to a point within easy reach of the operator.

In operation the hand-lever II is moved laterally to move the tongue J and the sliding portion (Z of the clevis laterally on the bars a and Z) to give the plows more or less land, and inaybesecured in desired lateral adj ustment by the locking-bolt engaging the rack (Z; and to adjust the line of draft vertically the bar a may be shifted to the desired apertures a in the jaws a. To raise or depress the front ends of the beams A A, the lever M is depressed or raised and secured in desired adjustment by the locking-bolt engaging the teeth d of the rack L. The object of the spring is to cushion the plow and protect it from breakage by either the plows or the wheels coming against an obstruction, as in the event of the plow catching upon a root or rock the spring will yield to the blow or pressure, the lever M and the sliding segment L will move up and about. the central portion of the axles D and D to allow the front end of the beams to drop or the plows to rise, as the case may be, and in case the wheels 0 strike an obstruction the yielding of the spring will allow the wheel to yield or rise and pass over without doing violence to the wheel or materially interfering with the operation of the plows. To further control the movement of the plows to hold them up to a desired line, particularly on the side of a hill, where the tendency is to slide or move away from the land, a furrow-wheel N, having a swiveled connection with the supporting-frame, is provided, having its axis fixed in the free end of the yoke 71, said yoke secured at its front end in vertical adjustment to the shaft 7L, journaled or swiveled in the frame I by the set-screw 715 said shaft having at its upper and lower end portions removable collars by which it is held in adjustment in the supporting-frame. At the upper end of the sleeve portion h of the yoke h is provided an upwardly-projected lug It". On the shaft h is placed a hub portion M having recesses 7r" and 70, as shown in Fig. 5. Said hub is held against the sleeve 72? by the downwardly-exerted energy of the coil-spring 7r", placed about the shaft h, the upper end of the spring to take under the collar 7t". A foot-lever Q is provided, having at its rear end prongs 7;, the ends of which are rounded and adapted to take in the sockets 7L7 in the hub 71 the lever resting on and pivoting over the arm 7;, secured to the frame P. At the front portion of the lever is pro vided a foot-piece and a stud or pin 7& to engage the teeth 7,1, provided on the front ed ge of the foot-rest R. In operation the sleeve if of the wheel-yoke 7b is locked to the hub h bythelughenteringthesocketh The lever Q, engagin the rack h 011 the foot-rest R, will hold the wheel N to a desired line, which may be varied by moving the front end of the foot lever laterally and engaging it with the rack at desired adjustment, giving the desired lead to the wheel, by which the rear port-ion of the plows may be inclined either to the right or left, as the case may be, and at the turningpoint the lever Q, may be passed down to raise the hub h above the lug Ii to allow the wheel N to turn freely about its swiveled connection with the frame 1 to allow the plows to be more easily turned at the point of turning. lIavin g thus fully described the nature and object of my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the plow and the cranked axle-shaft, of the curved standard, a rack to slide on said standard, a spring to resist the movement of said rack, and a hand lever to engage the rack, substantially as de scribed, and for the purpose set forth.

2. The combination, with the plows and the beams A and A, the cranked axle D and D, of a yielding rack and a hand-lever to engage said rack, substantially as described, and for the purpose set forth.

3. The combination, with the plows and the beams A and A, of a clcvis to engage the front ends of said beams, consisting of the jaws a, a bar a, connecting said jaws, a sleeve (6 to slide on said bar, said sleeve having a loop a and a perforated plate portion a and a hand-lever by which said sleeve may be moved laterally and secured in desired adj ustment, substantially as described, and for the purpose set forth.

a. The combination, with the plows and the beams A and A, of the clevis-jaws secured to said beams, a bar 1) to connect said jaws, a tongue-support having a sleeve portion Z) to slide on said bar, a link portion 7)", and a hand-lever II, by which said sleeve and tongue may be moved laterally on said bar simulta neously with the clevis, substantially as described, and for the purpose set forth.

5. The combination, with a plow, of a rear furrow-wheel swiveled thereto, a wheel-supporting yoke having lugs h and a vertical shaft or spindle h, a hub it about said shaft, having recesses to engage said lugs, a coilspring to hold said lugs and recesses in engagement, and a foot-lever having one of its ends to engage said lug, the other to engage a rack by which said wheel may be held in desired adjustment and released to turn freely about its pivotal connection with the plow, substantially as described, and for the pur' pose set forth.

In testimony whereof I have hereunto set my hand this 23d day of June, A. D. 1800.

LEWIS GIBBS.
